Study of Preparation, Properties and Applications of Graphene

Abstract

As a two-dimensional nano-material with outstanding characteristics, graphene is mainly composed of carbon atoms organized in a honeycomb configuration. Numerous attempts have been made to produce substantial amounts of graphene using various chemical processes since the first isolation of graphene in 2004 by mechanical exfoliation from graphite. There is still a lot of potential applications remained undiscovered, particularly in strengthen heat resistance and toughness of the material. This paper summarized the preparation process of graphene, micro-morphology and macro performance of graphene in recent years. The mechanical properties, ways of toughening composites and mechanism of graphene on ultra-high temperature ceramic matrix were studied. In addition, the influence on thermal properties via different synthesis process, thermal shock resistance and oxidation resistance of graphene were explored.
